1 Claim. 1

This invention relates to a new and improved combination window and storm window construction.

A principal object of this invention is to provide a window and storm window combination wherein both the window and the storm window may be readily serviced from the inside of the building in which the window is positioned.

An important object of this invention is the provision of means in a combination window and storm window wherein the regular window is mounted on hinges for inward swinging and the outer storm window is mounted on a hinged main frame for outward swinging and the main frame having an inner auxiliary frame for rotational swinging about a vertical axis.

Another important object of this invention is to supply in a combination window and storm window means for easily removing the storm window and replacing it by ascr'een or vice versa from within the building in which the window is mounted.

A further object of this invention relates to a combination window and storm window. construction in which there is effective sealing mean between the outside and the inside of the building. A still further object of this inventionis to provide means in a window construction for mam! facture from. either metal or wood.

Another and still further important object of this invention is the provision of means for slidably removing an outer storm panel from within the interior of a building.

Still another important object of this invention lies in the construction of a window wherein effective circulatory ventilation may be had with out opening the window on its hinges.

Another important object of this invention lies in the fabrication of a combination window and storm window wherein the storm window portion may be swung about on a vertical central axis for washing or servicing and also may be slid out for replacement by a screen or the like.

Other and further important objects and advantages will become apparent from the disclosures in the following specification and accompanying drawings.

In the drawings:

Figure 1 is a front or inside elevational view of the combination window and storm sash of this invention.

Figure 2 is a rear or outside elevational view of the device as shown in Figure 1. I V I Figure 3 is a sectional view taken on the line 33 of Figure 1.

Figure 4 is a sectional view taken on the line 4-4 of Figure'z.

Figure 5 is a sectional view taken on the line 5--5 of Figure 2.

Figure 6 is a sectional view taken on the line 8-6 of Figure l.

Figure 7 is a top plan view or the window of Figures 1 and '2 and showing the various hinging and sliding movements of the window and storm window.

As shown in the drawings:

The reference numeral l indicates generally a generally rectangular window frame to be mounted integrally with the wall of a building. An inner regular window sash frame II is positioned in the frame Hi 'so that it lies within and adjacent the interior of the building. The sash frame II is arranged and constructed to swing inwardly about hinges I2 and 13 which are fastened to the sash and to the frame 10. A latch element [4 is carried on the sash frame I I and has cooperative holding engagement with a complementary latch element mounted on the frame I!) when the sash frame l is in closed Dosition with respect to the frame 10. I

The sash frame H comprises a centrally disposed fixed glass section, a top openable section 41, and a bottom openable section I8. A dividing board 19 is positioned between the top section I! and the center section 16. Similarly a dividing board 20 is disposed between the juncture of the center section i6 and the bottom section l8. The top openable section 1 l of the window sash frame H includes transversely sliding separate panes 2i and 22 which may be adjusted relative to each other to permit passage of various quantities of air. The bottom openable section 18 of the Window sash frame H is provided with transversely sliding panes 23 and 26 in the same manner as the top section. It should thus be apparent that proper and efiective room ventilation may be obtained by opening the top and bottom sections l! and 'l 8 of the window sash I l An auxiliary frame for receiving a storm or screen sash is mounted for outward swinging movement with respect to the frame I 8 by means of hinges 26, 21, and 28. The rear positioned auxiliary frame 25 is preferably made of metal and is rectangular in shape having spaced side angle members 29 and 30 and top and bottom angle members 3| and 32 respectively. It should be noted that the side angle members 29 and 30 are disposed opposite directions. A hook or other lat-ch means is mounted on the frame ii) for engagement with an eyelet or other cooperaon a centrally disposed vertical pivot member 38. The pivot member 38 engages the cross member 31' and is journaled within the top angle member 3| of the auxiliary frame 25. Similarly a bottom cross member 39 is mounted for pivotal movement on a central vertical pivotAO joining the bottom cross member 39 to the bottomangle32 The Pivot pins 38.

of the auxiliary frame 25. and 40 are in vertical alignment in the center of the storm sash auxiliary frame 25.

A storm window sash frame 4| is. slidably mounted within the top and. bottom cross members 31 and 39. The top cross member 31 is equipped with a grooved track 42 across the underside thereof. Similarly the bottom cross member 39 is equipped with a grooved track 43 across the topside thereof. The storm sash frame 4| is provided with raised track tongue or rib members 44 and 45 across the top and bottom respectively. The track tongue 44 is adapted to slidably engage the track groove 42 in the cross top member 31 and the track tongue 45 is adapted to slidably engage the track groove 43 in the bottom cross member 39 in the same manner.

The storm sash frame 4| is equipped with an upper window glass section 46 and 'a lower window glass section 41. The upper and lower sections 46 and 41 are separated by a dividing board In operation the window frame I is positioned within a building wall wherein one side faces the interior of the building and the other side the exterior. The regular window sash H is positioned on and in the interior side of the window frame. Ordinary ventilation is accomplished through the transversely sliding panes of the upper and lower sections of the window sash. However, in opening the entire sash about its hinges l2 and I3 the sash swings inwardly into the interior of the building about an arc designated by the numeral 49. As previously stated the cooperative latch means l4 and I hold the window against undesired inward swinging. When the latch members I4 and I5 are released one from the other the sash may be swung inwardly in the path of the arc 49 whereafter the sash may then be washed or serviced from within the building. Further'the full inward swinging of the regular sash permits access to the storm or' screen sa h mounted on the exterior side of the frame l0.

After the regular sash is swung open the hook and eyelet means 33 and 34 are disconnected thus permitting outward swinging of the auxiliary storm sash frame about its'hinges 26, 21, and 28 in an'arc designated by the numeral 59 as shown in Figure '7. In order that washing or servicing of the outside of the sash frame 4| may be accomplished it is swung about its aligned vertical pivot pins 38 and in the manner shown by the arc 5| in Figure '7. It is now apparent that access for washing or other servicing may be had from, the interior of the building for all four faces vof the regular sash and storm sash form without change.

of this combination window. It should also be noted that the reverse positioning of the side angle members 29 and 30 of the auxiliary frame 25 as shown in Figure 6 prohibits reverse swinging of the storm sash on the auxiliary frame members and provides a substantial stop for a true home or closed position of the storm sash frame 4| within the auxiliary frame 25. The storm sash auxiliary frame 25 is also provided with stop means in the form of the flanges of the top and bottom angle members 3| and 32 for engagement with the window frame [0.

The movements of the combination window elements thus far described are concerned solely with servicing of the combination window in one As stated in the objects above an important phase of this invention is to facilitate changing from storm to screen sash ee -W- or vice versa without climbing up to the window from the outside of the building. As best shown in Figure 7 the storm sash frame 4| may be slid out from the top and bottom cross members 31 and 39 by reason of the interenga ing track elements 42 and 44, and 43 and 45. The storm sash frame is not removable by sliding when the sash is in closed position with respect to the auxiliary frame 25. The sash must preliminarily be swung through the arc 5| whereafter the sash may be slid longitudinally in or out on the tongue and groove tracks of the top and bottom cross members. The sash being slidably removed is shown in the dashed line position as designated by the numeral 52. By so operating the window the storm sash may be moved directly to the interior of the building with a minimum of effort and consequently a screen sash may be reinserted in the tracks of the top and bottom cross members for hot weather use of the combination window.

Numerous details of construction may be varied throughout a wide range without departing from the principles disclo ed herein and I therefore do not propose limiting the patent granted hereon otherwise than as necessitated by the appended claim.

I claim:

In a window construction comprising a rectangular frame structure. an auxiliary frame, means mounting said auxiliary frame for hin ed swinging movement with respect to said frame structure, top and bottom cross members disposed within said auxiliary frame, vertical hinge means formed on and positioned centrally of said top and bottom cross members, means journaling said vertical hinge means in said auxiliary frame, a window sash frame carried by said top and bottom cross members, said window sash frame and said top and bottom cross members having interlocking tracks permitting relative longitudinal sliding movement of the window sash frame within the top and bottom cross members, said auxiliary frame including spaced side angle members in reverse position to provide limit stops for the top and bottom cross members and their included window sash frame pivoting on the vertical hinge means. v
